I am not able to create the crash with a pre-processed file.(don't know
why?) So can't give a pre-processed file. Any ideas?

But that surely is a seperate bug.

Can you build a more recent native compiler like 3.3.2 and then try again?

OK I will try building with 3.3 release as a native compiler.

Do you think it is related to some 2.96 bug or is it 
because you have a recent build environment for confirming bugs
and this does not occur in your environment or something else?

The former, I have not tried to build sh-elf yet with the tree-ssa on i686-pc-linux-gnu but since 
2.96 is not a support GCC release, I want to eliminate that variable.

This is to confirm the crash, when sources are compiled:

$ gcc -v
Reading specs from /usr/local/lib/gcc-lib/i686-pc-linux-gnu/3.3.1/specs
Configured with: ../gcc/configure --enable-languages=c,c++

The bug seems to be fixed or buried as of now. I don't get this problem
anymore. I hope it doesn't show up again. Please close the PR for now.
Thanks !!
